To William F. Snodgrass Communications Director Company Name
City, State, Zip Code
Dear Mr. Snodgrass,
I am writing this letter because I am afraid that I must resign from the current freelance writing work I am doing for your company. Due to the fact that I have already provided the two rewrites I initially agreed to in our contract for a predetermined price and that you are unable to increase your budget on this project, I must remove myself from further work on it at this time. My resignation is official immediately, Friday September 19, 2014, as I have already completed the work laid out in our contract.
Please understand I have enjoyed working with you, but I am simply unable to put forth any further time and talent without additional compensation. It is unfortunate that we have reached such an impasse. I do, however, believe it is in my best interest to resign from your service.
I hope you will be able to find an alternate freelance writer or in-house employee who can complete the project to your satisfaction. I wish you well in future endeavors.
